FHIR Resource Definition: Union of UDS Plus Clinical Result Observation

Details

This document provides the unified definition for the `uds-plus-clinical-result-observation` resource within the FHIR standard. This resource is designed to handle observation results, incorporating detailed metadata such as who, when, and in what clinical event (Encounter) the measurement was taken. Structurally, it defines fields beyond basic FHIR elements, including `subject`, `encounter`, `category`, `code` (classification and type of observation), and `effective[x]` (clinically relevant time). The name 'De-Identified UDS Plus' suggests its intended use in anonymized datasets. Technically, it establishes constraints on standard FHIR elements (e.g., `meta`, `identifier`, `extension`) alongside specific business logic (e.g., `obs-6`: dataAbsentReason must only be present if Observation.value[x] is not present). These specifications are crucial for ensuring data quality and consistency in healthcare information exchange.
